[0043] Gua Sha is a traditional Chinese therapy. It uses special scraping instruments and corresponding techniques to repeatedly scrape and rub the body surface, causing local red millet-like or dark red bleeding spots to appear on the skin, thereby achieving the effect of promoting blood circulation and removing the sha. With the development and progress of science and technology, the emergence of handheld scraping instruments has brought a lot of convenience to people. People can do scraping at home without going to a physical therapy center or a traditional Chinese medicine clinic for scraping. However, the current scraping instruments generally have a single function, and only have the effect of heating scraping, and the physical therapy and health care effect is limited.

[0054] Preferably, the heating module 4 of the present application adopts a graphene electric heating film. By supplying power to the graphene electric heating film, the graphene electric heating film emits far-infrared rays to act on the human body. The far-infrared rays released by graphene heating are called "life light waves", which are very close to the far-infrared waves of the human body. They can "resonate" well with the water molecules in the cells of the body, promote the expansion of the human body's microvessels, make blood circulation smooth, promote metabolism, and enhance the body's immunity and cure rate.
[0055] The light-transmitting body 5 may be a flat plate structure or an arc-shaped body so as to better fit the human body surface.

[0058] It can be understood that the heat energy generated by the heating module 4 is transmitted to the outside in the form of far-infrared radiation. The connecting body 201 is covered on the light-transmitting body 5. The far-infrared rays can quickly act on the scraping element 202, so that the heat can be conducted to the scraping element 202 faster.
[0059] Specifically, the scraping piece 202 may be made of, but not limited to, jade, ox horn, flat stone, porcelain, wood fragrance, etc. Preferably, the scraping piece 202 of the present application is made of jade, which can generate far infrared rays, ultra-long waves and negative ions after heating, and has a good therapeutic effect on the human body.
[0060] In some embodiments, the shape of the connecting body 201 matches the shape of the translucent body 5 ; the connecting body 201 includes a peripheral portion 6 , which is covered on the translucent body 5 and allows the peripheral portion 6 to cover the outer wall of the care head 3 .
[0061] Specifically, the shape and structure of the connecting body 201 is matched with the shape and structure of the light-transmitting body 5, so that after the two are connected, the structural integrity is good.
[0062] For example, refer to Figure 1 , Figure 2 The light-transmitting body 5 can be designed as a rectangular structure, and the connecting body 201 is correspondingly configured as a rectangular structure matching the light-transmitting body 5 ; the scraping member 202 is a plate-like structure arranged on the connecting body 201 .
[0063] Or, refer to Figure 4 , Figure 5 The care head 3 can be set to a circular structure, and the connecting body 201 is correspondingly set to a circular structure matching the light-transmitting body 5; and a hollow structure is provided in the middle of the connecting body 201, so that the far-infrared light can better pass through the connecting body 201, and the scraping element 202 is a bead structure evenly arranged on the connecting body 201.
[0064] The outer edge of the connecting body 201 has a circle of peripheral portion 6, and the peripheral portion 6 can cover the outer wall of the care head 3, so that the connecting body 201 and the care head 3 form a limited fit, and the two are tightly connected.
[0065] refer to Figure 2 , Figure 3 In some embodiments, a connecting portion 7 is provided on the peripheral portion 6, and a connecting fitting portion 8 is provided on the outer wall of the care head 3; the connecting portion 7 is detachably connected to the connecting fitting portion 8.
[0066] Specifically, the peripheral portion 6 is connected to the care head 3 via a connecting portion 7 and a connecting matching portion 8, and the specific connection method may be, but is not limited to, plug-in, snap-in, and the like.
[0067] In some embodiments, the connecting portion 7 is a card block arranged on the peripheral portion 6, and the connecting mating portion 8 is a card slot arranged on the outer wall of the care head 3. The peripheral portion 6 covers the outer wall of the care head 3 and the card block is connected to the card slot, so that the connection between the scraping assembly 2 and the care head 3 is convenient and quick.
[0068] It can be understood that the connecting body 201 is light-transmissive, and the far infrared rays released by the heating module 4 can also penetrate the connecting body 201 to act on the human body surface. In addition, the connecting body 201 has a certain plasticity, and then the connecting body 201 can be quickly assembled or disassembled with the care head 3 under the action of external force.
[0069] refer to Figure 2 In some embodiments, the light-transmitting body 5 forms a plurality of protrusions 9 protruding outward on the contact surface 301 .
[0070] It can be understood that the protrusion 9 can better stimulate the user's body surface and achieve a massage effect. A groove structure is correspondingly provided on the connecting body 201 to avoid the protrusion 9, so as to prevent the connecting body 201 from interfering with the care head 3.

[0074] Specifically, the battery 1102 can supply power to the heating module 4 and the vibrator 10 respectively, so that both can operate stably. A charging interface 12 is provided at the bottom of the housing 1, through which the battery can be charged.
[0075] It can be understood that the battery 1102 can supply power to and cut off power to the heating module 4 and the vibrator 10 under the control of the control circuit board 1101. A control panel 13 is provided on the outer wall of the housing 1, and the control panel 13 is electrically connected to the control circuit board 1101. The control panel 13 can be a panel with a display touch function. A plurality of adjustment buttons are formed on the control panel 13. By acting on the adjustment buttons on the control panel 13, the heating module 4 and the vibrator 10 can be started and stopped, and then the nursing device 100 can be controlled to start or shut down, making the user operation more convenient.

When the scraping assembly 2 is combined with the care head 3, the control circuit board 1101 controls the heating module 4 to be in a high-power heating mode, which can quickly transfer heat to the scraping member 202; when the scraping assembly 2 is separated from the care head 3, the control circuit board 1101 controls the heating module 4 to reduce the power to prevent the contact surface 301 from being too hot and scalding the user.
[0078] Specifically, the sensing part 14 is a magnetic sensing chip disposed in the shell 1 , and the sensing matching part 15 is a magnet disposed on the connecting body 201 , which can accurately sense the connection state between the scraping assembly 2 and the care head 3 .

[0080] Specifically, the light source module 16 uses a lamp bead sheet or a lamp bead board that can release red light or blue light, and the battery 1102 is controlled by the control circuit board 1101 to supply power to the light source module 16 .
[0081] The light source module 16 releases red light or blue light through the light-transmitting body 5, and uses the red light beam to irradiate the human body surface, which can repair abnormal skin tissue, stimulate inflamed and aged skin, promote faster recovery of the disease, and achieve a therapeutic effect. The blue light has the effect of disinfecting and sterilizing the skin surface, further improving the nursing effect of the nursing device 100.
[0082] It can be understood that buttons for controlling the light source module 16 are formed on the control panel 13 to facilitate the user to control the start and stop of the light source module 16 .
